Worldcoin’s World ID Expands to Solana via Wormhole Grant

Wormhole
contributors
have
been
awarded
a
grant
from
the
Worldcoin
Foundation
to
bring
World
ID,
a
leading
decentralized
identity
protocol,
to
Solana.
This
integration
aims
to
enable
Solana-based
protocols
to
seamlessly
verify
users’
World
IDs
originally
authenticated
on
Ethereum,
showcasing
the
versatility
of
Wormhole’s
multichain
infrastructure.

Primer
on
Worldcoin,
Wormhole,
and
Solana

Worldcoin
is
a
decentralized
identity
protocol
designed
to
provide
universal
access
to
the
digital
economy.
It
employs
privacy-preserving
cryptographic
techniques
like
zero-knowledge
proofs
to
verify
identities
without
compromising
user
privacy.
The
core
of
Worldcoin
is
the
World
ID,
which
uses
biometric
data
to
ensure
secure
and
fair
identity
verification.

Wormhole
is
a
decentralized
interoperability
protocol
facilitating
data
and
asset
transfers
across
different
blockchain
networks.
Launched
in
2021,
it
supports
over
30
blockchains
and
processes
approximately
$30
million
in
daily
funds.
Wormhole’s
infrastructure
allows
developers
to
build
applications
that
operate
across
multiple
blockchains.

Solana
is
known
for
its
high
performance,
scalability,
and
low
transaction
costs.
It
can
handle
up
to
65,000
transactions
per
second
(TPS)
due
to
its
innovative
Proof
of
History
(PoH)
consensus
mechanism.
This
makes
Solana
an
ideal
platform
for
deploying
decentralized
applications
requiring
high
throughput
and
speed.

Technical
Integration

The
primary
objective
of
this
integration
is
to
enable
protocols
on
Solana
to
verify
users’
World
IDs
authenticated
on
Ethereum.
This
involves
two
main
tasks:

1. Reading,
   authenticating,
   and
   propagating
   the
   World
   ID
   state
   root
   from
   Ethereum
   to
   Solana.
2. Allowing
   protocols
   on
   Solana
   to
   authenticate
   users’
   World
   IDs
   against
   the
   canonical
   state
   root
   stored
   on
   Ethereum.

A
new
smart
contract
on
Solana,
the
SolanaWorldIDProgram,
will
verify
and
store
World
ID
state
roots
and
validate
inclusion
proofs.
Wormhole
Queries
will
be
used
to
authenticate
inclusion
proofs
until
Solana’s
bn254
syscall
is
available
in
the
upcoming
1.18
release.
The
Ethereum
to
Solana
Wormhole
State
Bridge
Service
will
propagate
the
World
ID
state
root
from
Ethereum
to
Solana.

Why
Does
Worldcoin
x
Wormhole
Matter?

This
integration
simplifies
incorporating
World
ID
verification
for
Solana
protocols.
Standard
APIs
and
libraries
will
be
provided
for
easy
implementation.
The
integration
is
designed
to
be
forward-compatible,
accommodating
future
updates
and
improvements
in
verification
methods.

Additionally,
the
integration
brings
several
broader
benefits:

• 
  Enhancing
  Security
  and
  Decentralization:
  It
  improves
  security
  and
  decentralization
  of
  identity
  verification
  across
  blockchain
  networks,
  preventing
  fraud
  and
  ensuring
  fairness.
• 
  Facilitating
  Cross-Chain
  Interoperability:
  It
  exemplifies
  the
  power
  of
  cross-chain
  interoperability,
  enabling
  decentralized
  applications
  on
  Solana
  to
  interact
  with
  identity
  verification
  systems
  on
  Ethereum.
• 
  Promoting
  Financial
  Inclusion:
  By
  making
  identity
  verification
  more
  accessible
  and
  secure,
  more
  people
  worldwide
  can
  participate
  in
  the
  digital
  economy,
  promoting
  financial
  inclusion.

Conclusion

The
integration
of
Worldcoin’s
World
ID
with
Solana,
facilitated
by
Wormhole,
represents
a
significant
development
for
Web3.
It
enhances
security,
decentralization,
and
cross-chain
interoperability,
promoting
a
more
inclusive
digital
economy.
The
SolanaWorldIDProgram
and
the
Ethereum
to
Solana
Wormhole
State
Bridge
Service
provide
a
robust
and
scalable
solution
for
cross-chain
identity
verification.
